I'm trying to compile Emacs with pgtk support from the current master
(4edb7713) but after I run the configure script with --with-x-toolkit=no
and --with-pgtk I get the following error:

    checking for gtk+-3.0 >= 3.22.23 glib-2.0 >= 2.37.5... no
    configure: error: 

I have gtk+3 version 3.24.38 and glib version 2.78.0 installed. I am
running the Void Linux distribution with glibc, and I generated the
configure script with `autoreconf -fi'. The full output log is attached,
would anyone be able to help here?
